Bearded iris are easy to cultivate and propagate and have become very popular in gardens. A small selection is usually held by garden centres at appropriate times during the season, but there are thousands of cultivars available from specialist suppliers (more than 30,000 cultivars of tall bearded iris). They are best planted as bare root ...
Some of these species have been bred with bearded irises to create unique colours and markings. [2] Oncocyclus is a Greek word, with onco meaning mass, or bulk, and cyclus meaning circle. [ 9 ] In 1846, the term 'Oncocyclus' was first used by C.H. Siemssen as the Genus Oncocyclus in 1846 in Botanische Zeitung.

As most irises are diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings. [5]: 18 It has a chromosome count of 2n=40. [3] [4] [6] It was counted by Colasante & Sauer in 1993 and by Colasante in 1996. [2] It is the same as Iris setina, Iris bicapitata, Iris lutescens and Iris revoluta. [7]
In 2012, a study was carried out on 4 diploid and 7 allopolyploid bearded Iris species. Their leaf flavonoid, isoflavonoid and xanthone constituents were investigated. It also found that Iris bicapitata had a chromosome number of 2n=40, and was a parent species of Iris germanica and Iris albicans (who are counted as 2n=44).
